Time-of-day metering is a rate option that is offered by many utilities. When elected by the customer, a meter that records time, and energy usage is installed in place of the existing electrical meter. The metering option benefits utility companies by decreasing the required capacity and customers by providing reduced demand and usage rates during off-peak times, which gives customers a chance to reduce their utility bill. The meter offers a flexible tariff structure. This feature provides a useful way of following different tariff structures during different times of the day for different seasons.

In power quality setup, user can set threshold levels for sag, swelland overcurrent detection. Also user can enter the harmonic no whichuser want to observe.

For threshold setup click on threshold setup menu. For sag level,touch the sag level menu and enter the value. The valid threshold level for sag is from 10 % to 90 % of nominal.If user enters wrong value then it will display “INVALID VALUE” and will display the valid range. Similarly threshold value for swell and overcurrent can be configured. The valid range for swell and overcurrent is 110 % to 150 % of nominal value. PT Secondary is considered as nominal value.

In harmonic setup, user can define the order of harmonics that userwant to observe for each phase. Maximum 6 different harmonics number can be configured at a time. For setting of harmonic, touch on the rectangle and enter the number. Valid range for harmonic no is from 2 to 56. Entering wrong value will display “INVALID VALUE” and will show the valid range.

Connection should be made using twisted pair shielded cable. All "A" and "B" connections are daisy chained together. The screens should also be connected to the “Gnd” terminal. To avoid the possibility of loop currents, an Earth connection should be made at one point on the network.Loop (ring) topology does not require any termination load. Line topology may or may not require terminating loads depending on the type and length of cable used. The impedance of the termination load should match the impedance of the cable and be at bothends of the line. The cable should be terminated at each end with a 120 ohm (1/4 Watt min.) resistor.

RS 485 network supports maximum length of 1.2km. Including the Master, a maximum of 32 instruments can be connected in Rs485 network.The permissible address range for the

Accessing Sag, Swell, Over Current data through MODBUS : The Sag, Swell, Over Current time stamping data can be accessed from the addresses shown in table 5. In this case Hour & Minute parameters are combined on one location and Date, Month & year parameters are combined on the next location.For example: Suppose after reading register 30581, data read is 1051 in decimal. And reading register 30583, data read is 150313. Here in 1051, first two digits stand for hour i.e 10Hours and the next two digits stand for minute i.e 51 minutes. Also in 150313, first two digit denotes date i.e 15, next two denotes month i.e 3 and last to gives year when added to 2000.So, For address 30581 10:51 is time for SAG 1. For address 30583 15 / 03 / 2013 is date for SAG 1.Sag, Swell, Over Current data is applicable in both 3P3W & 3P 4W.Table 5 : 3 X register (Sag, Swell, Over Current data)

Accessing 3 X for reading Time Of Day data : Time Of Day data can be read from 3 X register only after setting the 4 X register address 40083 (parameter No. 41 in 4 X register). For different values in 40083 different TOD data can be read. Settings for 40083 address are mentioned in table 6.

Table 6 : TOD Data Configuration

70

If value at 40083 is configured from 1 to 6 , the corresponding data in 3 X register can be read for maximum 5 minutes. After that 40083 will automatically be configured as 0 , and normal measured parameter will be held in 3 X register. For Time Of Day data the units for energy and cost multiplier are decided on the settings of Pt primary value and CT primary value. Following table shows the unit of energy and cost multiplier for the different ranges of CT primary and PT primary.

For example, Suppose PT primary value is set as 500 and CT primary value is set as 5, then 5 * 500 * 1.732051 = 4330.127. This is less than 900 KW.So the per month energy , per day energy & per zone energy will be in KW. Also cost multiplier for all cost will be 1. In other case, if PT primary value is set as 692800 and CT primary value is set as 1157, then 1157 * 692800 * 1.732051 = 1388359273. This is greater than 90000 KW. So the per month energy , per day energy & per zone energy will be in KW. Also cost multiplier for all cost will be 1000 i.e. if get value of cost as 5 , cost should be

12.1 EMC Installation RequirementsThis product has been designed to meet the certification of the EU directives when installed to a good code of practice for EMC in industrial environments, e.g.

1. Screened output and low signal input leads or have provision for fitting RF suppression components, such as ferrite absorbers, line filters etc., in the event that RF fields cause problems.

Note: It is good practice to install sensitive electronic instruments that are performing critical functions, in EMC enclosures that protect against electrical interference which could cause a disturbance in function.

2. Avoid routing leads alongside cables and products that are, or could be, a source of

Caution1. In the interest of safety and functionality this product must be installed by

a qualified engineer, abiding by any local regulations.

2. Voltages dangerous to human life are present at some of the terminal connections of this unit. Ensure that all supplies are de-energised before attempting any connection or disconnection.

3. These products do not have internal fuses therefore external fuses must be used to ensure safety under fault conditions.

As the front of the enclosure conforms to IP54 it is protected from water spray from all directions, additional protection to the panel may be obtained by the use of an optional panel gasket.

The terminals at the rear of the product should be protected from liquids.

The instrument should be mounted in a reasonably stable ambienttemperature and where the operating temperature is within the range

0-10 to 55 C . Vibration should be kept to a minimum and the product should not be mounted where it will be subjected to excessive direct sunlight.

interference.

140

4. ESD precautions must be taken at all times when handling this product.

3. To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source. The unit has been designed to automatically recover in the event of a high level of transients. In extreme circumstances it may be necessary to temporarily disconnect the auxiliary supply for a period of greater than 5 seconds to restore correct operation.

The Current inputs of these products are designed for connection in to systems via Current Transformers only, where one side is grounded.
